Put the eggs into a medium pot, cover with water, and bring to a boil. Boil for nine minutes, then drain and place into a bowl of cold water.
Peel the eggs and place into a medium mixing bowl. Once all the eggs are peeled, break the eggs up with your hands.
Chop up your cornichons, capers and herbs and add to the bowl.
Add the dijon and wholegrain mustard, along with 2 tbsp of mayo and 2 tbsp of extra virgin olive oil. Season with salt and pepper.
Zest about half of the lemon and add half of the juice - if it needs more, add more zest and juice.
Mayo up the bread, and dollop egg salad mixture liberally. Enjoy.
